This solution works given the fact that I know what type of data
I want to add and I can't see a situation where that isn't the
case. In Juan's case, he wanted to add an error code so he _knew_
already what type is required (int).
It seems we did a full circle. I'll ask again, what are you
trying to optimize here? Number of instantiations?
